Be it known that I, CALEB MARSHALL TAYLOR, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Floor Coverin s and Processes of Making the.

Same, 0 which. the following is a specification. v

This invention relates to floor coverings and to the process of making the same, and is particularly dir ted. to the manufacture of felt basefloor coverings. The present invention provides-a transparent, flexible and-tough wear coat over the surfaceofthe paint coat or coats, and in contrast to=the wearing quality of paint, it provides a surface of material not easil saponifiable', which will resist the action 0 soap and water.

In the accompanying drawing there is illustrated the relative position of the wear coating with respect" to the base. Figure 1 represents an enlarged sectional View showing a-felt base 1 covered withtwo coats of palnt, lin which has been previously prepared in accordance with the details hereinafter set Figure 2 is a plan view of the material shown in Figure 1. indicating the transparency of the other coat. Referring in detail to each of the figures of thedrawings, 1 indicates the felt base, 2 a sealing coat of paint, 3 a decorative paint coat, and 4 the outer wear coat of the cellulose ester material.

The floor covering of thepresent invention may be prepared by usingethe. impregnated base. uch a base may the present known asphalt or bitumen impregnated felt,

or the base may be prepared y impregnating with a saturant solution of a cellulose ester asdescribed in my copending applicaouter coating tion, Serial No. 528,297, filed January 10, 1922.

paint and the paint coat is thendried. An

then applied by dipping the painted base or by brushingthe solution over the pa nt coat, or by spraying, or by any suitable spreading means, and finally the cellulose es-- ter coating is dried. V y Inthe preparation of the cellulose coating solution acetyl cellulose may be used instead of nitrocellulose.

terial of the outer coating, a

and having an outer coat of pyroxy weight of butyl alcohol,

The completed base-is coated with.

of a cellulose ester solution 'is' of the outer coating may be made by using twenty parts by weight of dry pyroxylin,

nitro cotton, in a solvent mixture compo of thirtyparts of either 'or both butyl alcohol'or' amyl acetate plus parts b Weight 'of anhydrous denatured et y Twenty to thirty parts by weight? of raw castor oil is added as a softener. Tricresylpho's hate or diethyl or dibutyl thalate may be use as softeners, using these in the same alcoho proportions as the raw castor oil is specified.

. To get the proper consistency for the mat inner, under would be a mixture of r amyl acetate with the ured ethyl alcohol. In roportion of the solvent ordinary conditions, either the butyl anhydrous dena other words, the

'may be varied s ightly as the conditions vary, according to the judgment of the worker. In case the humidity is very high, a thinner consisting of 50% of either butyl or amyl alcohol and 50% butyl or amyl acetate may be used as a thinner in order to eliminate the blush.

Another satisfactory solution for the inaterial of the outer coating may made by using 20 parts by weight of pyroxylin, and a I solvent "mixture composed .of 12 parts by 18 parts by weight of ethyl acetate, and 30 parts b weight of anhydrous denatured ethyl alco 01. To this mixture should be added 15 or 20 parts by weight of raw castor oil..

These solutlons are peculiar in that they paint coat when the solution for the film applied directly to the paint.

do not tend to soften, dissolve or remove the 7 The floor covering embodying this invention may be used without the need of spacing paper in the shipment of such floorcoverings, whether the coverings are roll form or stacked inla ers. Heretofore it has been necessary to ave s acing paper between adjacent layers in or er to prevent the paint coats from adhering. I Thematerial ossesses good wearing qualities and is toug and flexible, and does not soilv as readily as paint service.
